Let φ be a locally upper bounded Borel measurable function on a Greenian open set Ω in Rd and, for every x∈ Ω, let vφ(x) denote the infimum of the integrals of φ with respect to Jensen measures for x on Ω. Twenty years ago, B.J. Cole and T.J. Ransford proved that vφ is the supremum of all subharmonic minorants of φ on X and that the sets \vφ
